Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Enforces verification of the source of a communication channel by requiring identification and authentication of services first.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Requires explicit verification of the source and integrity of the channel used for authentication and other security functions.
Provides the means to verify the source of name-resolution responses instead of relying on unauthenticated channels.
Requires explicit verification of the communication source, blocking session hijacking via spoofed or alternate channels.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Authentication of users/services/hardware directly enforces source verification for communication channels.
Verifying identity assertions prevents spoofed channel origins but does not cover all channel-establishment scenarios.
Secure SDLC practices directly require and enforce input validation during development.
Network protections reduce unauthorized channel usage but do not specifically require origin verification at channel setup.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure authentication mechanisms verify the identity and origin of communication channel initiators.
Network security controls enforce source verification and channel authentication for incoming communications.
Security of network services includes validating the origin of service requests and connections.
Network segregation limits exposure but does not directly verify source of individual channels.
Cryptography can support channel authentication but does not inherently verify source without proper implementation.
